CopilotKit/OpenMuse ? reverse-engineered prompt

Build me a personal AI agent app called OpenMuse that works on web, iPhone, and Android, and can keep working in the background on tasks I give it.

I want to chat with it in a simple interface, ask it to browse the web, read email, check calendar items, work with files, and run commands in its own terminal or workspace. It should show me what it is doing as it goes, let me pause, stop, or take control of the browser session, and keep a clear task history with plans, progress, and saved results. It should also support things like reviewing a PDF, filling out a form, drafting a reply, and showing inline cards for browser, email, and documents so I can inspect the work before sending anything.

Make it feel like a real assistant with persistent memory, follow up tasks, and a clean mobile friendly UI. If you need to, look up current docs online for the best way to wire up CopilotKit and the agent flow.
